Some Orbital Mechanics Matlab Codes. Heavily based on the "Orbital Mechanics for Engineers, Howard D. Curtis" book.
A Rust package for the SGP-4 orbital propagator.
OrbMod (Orbit Modeling) - tools for numerical modeling of orbits: propagation and fitting to observations.
Versatile astrodynamics / space mission simulator. n-body orbital mechanics, maneuvers, perturbations and more.
Gauss-Radau Small-body Simulator. Maintainer: @rahil-makadia
Fast, accessible, accurate orbit propagator for spacecraft
High Precision Lunar Orbit Propagator
Codework for Orbit Propagation and Line-Of-Site Visibility Analysis using TLEs
The MATLAB model here presented performs trajectory propagations based on the Constant Density Polyhedron algorithm. With this model, it is possible to compute trajectories in the proximity of astronomical bodies such as asteroids or comets. The algorithm also allows to compute ballistic trajectories.
Outfit is a Rust library for orbit determination and propagation of small Solar System bodies, with support for MPC, ADES, Parquet, Gauss IOD, and JPL ephemerides.
Intuitive object-oriented library that simplifies orbital propagation for space missions.
Easy-to-use minor planet orbit propagator with animated orbits
